19 Claims. (Cl. 189-62) My invention relates to radiator shutters for automobiles and other automotive vehicles.

One of the objects of the invention is to pro-' vide an improved radiator shutter.

A further object of the invention is to provide an improved radiator shutter suitable for use with the radiator shell which is bent outwardly to give an arch or wide v effect.

A further object of the invention is to provide a radiator shutter having vertical shutter ele-'- ments arranged to impart an appearance of great depth to the radiator.

A further object of the invention is to provide a radiator shutter in which means are provided for the escape or removal of stones, insects and other foreign bodies which may enter between the shutter elements.

A further object of the invention is to provide a radiator shutter which furnishes a compartment between the shutter elements and the radiator core, so that the shutter opening may be effectively employed with a core of smaller size.

A further object of the invention is to provide a radiator shutter embodying improved means for operating a plurality of sets of shutter elements from a single operating device.

A further object of the invention is to provide a radiator shutter adapted to provide the shell with lateral support.

Other objects, advantages, and capabilities of the invention will appear from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings in which Figure 1 is a front elevation, partly in section, showing a radiator shutter embodying my invention, mounted within a radiator shell.

Fig. 2 is a sectional view therethrough, the shutter and. radiator core being shown in elevation.

Fig. 3 is a top plan view of the shutter.

Fig. 4 is a sectional view of same taken on the line 44 of Fig. 1.

Fig. 5 is a front elevational detail view showing a crank opening; and

Fig. 6 is a sectional detail view on the line 66 of Fig. 1.

Referring to the drawings, the radiator shell is designated by the numeral 10, the shutter as a whole by the numeral 11, and the radiator core by the numeral 12.

The radiator shutter 11 comprises a frame, which is constructed of two

side frame members

13 and 14, an upper frame member 15, and a lower frame member 16. The

side frame members

13 and 14 each comprise a vertical web 17 which is adapted to lie in a longitudinal vertical plane. The rear edge of the web 17 is turned inwardly as shown at 18 to provide a small strengthening flange. At its forward edge, the

web 17 gives into an inwardly and forwardly directed web 19, which is turned or rolled in the reverse direction to provide an outwardly directed web, which increases in width from the downward direction, as will readily be seen in Fig. 1.

Along its outer edge the web 20 gives into a forwardly directed web 21, the outer edge of which is bent outwardly to provide a flange 22 which is adapted to enter a bead in the face of the shell 10, as seen in Fig. 4. The web 20 may be provided with a longitudinal bead 23, which is parallel to the inner edge of the web 20 and imparts to said web an appearance simulating the shutters which are located between the side mem-

T bers

13 and 14, as will be hereinafter described.

The vertical webs 17 have secured thereto on their inner sides, preferably by spot welding blocks 24 which are provided with tapped openings in alignment with openings in the webs l7 and in openings and are threaded into the tapped openings in the blocks 24.

The lower frame member 16 comprises essentially a piece of sheet metal bent to an angle to provide a horizontal base portion 27 and a vertical apron 28 projecting vertically therefrom to a position adjacent the lower end of the radiator core 12. At its upper edge the apron 28 is ribbed as shown at 29 to strengthen same. At

each end the apron 28 carries an extension 30 which extensions are bent forwardly to engage the outer sides of the vertical webs 1'7 adjacent their lower ends, the flanges 18 being cut away to permit this engagement. The extensions 30 are welded to the vertical webs 17 or are secured thereto in any other suitable manner. Theforward edge of the horizontal base portion 27 is substantially in the form of a wide V, both sides of which are slightly convex. Around this edge the horizontal base gives into a vertical bead or web 31 upon which the inner edge of the lower portion of the shell 10 is adapted to abut. The metal of the bead 31 extends rearwardly and then downwardly to provide stiffness as shown in Fig. 6. Within the bead 31 is placed a bearing strip 32 which is secured to the underside of the base 27 along its forward edge. Openings extending through the base 2'7 and bearing strips 32 are provided to receive pintles of the shutter elements 33. The pintle openings are arranged in two series, one on each side of the center, each series being in a straight line.

The base 27 is provided with openings 34 whereby stones, bees, other insects, and other foreign bodies, which pass through the open shutters into contact with the radiator may escape. A crank opening 35 is provided in the apron 28 and.

is surrounded by a shield or box-like structure 36, which may be provided with flanges 37 by which it may be secured to the apron 28, for example by welding. The upper portion of the shield 36 is turned upwardly at its forward edge to provide a flange 38, behind which is mounted a short bearing strip 39, which provides openings for the lower pintles of the two center elements which are shorter than the remainder of the shutter elements to permit the provision of the crank opening 35.

The forward opening of the shield 36 may be closed in any suitable way. For example as shown in Fig. 5, the shell 10 may be provided with an extension 40 which lies over the forward end of the shield 36, said extension being pro- .Vided with an opening in alignment with the crank opening 35, which opening is provided with a conventional closure 41.

Or, as shown in Fig. 6, I may provide a closing plate 43 having rearwardly extending resilient members 44 adapted to enter the opening 35 and secure the closing plate 43 in position. As shown in Fig. l, the closure plate 43 is preferably ribbed to simulate the shutter elements, and is provided with a handle 45.

The upper frame 15 comprises a sheet metal plate 46 substantially corresponding to the shape of the base 27. Its forward and rearward edges are turned downwardly to provide

flanges

47 and 48 respectively, against which former flange the inner edge of the upper part of the radiator shell 10 abuts. Upon the lower side of the plate 46 is mounted a pair of bearing strips 49, holes extending through the plate 46, and the strips 49 to provide bearings for the upper pintles of the shutter elements 33. These openings 50 are positioned vertically above the openings in the base 27 and the openings in the bearing strip 49 and the shutter elements 33 are secured in position in said openings in the usual manner. At each end the plate 46 is provided with a downwardly directed lug 51 whereby it may be secured to the upper ends of the side frame membeam 13 and 14 by means of bolts 52.

As will readily be seen in Fig. 4, the shutter elements 33 are mounted in two series so that when they are closed, each element is directed away from the center. The shutter elements 33 shown on the right hand side of Figs. 3 and 4 are provided at their upper ends with rearwardly directed lugs 53 which are pivotally connected to a common actuating bar 54. The shutter elements of the series shown on the left hand side of Figs. 3 and 4, except the innermost element are provided with similar lugs 53 pivotally connected to a similar actuating bar 54. In order to provide for the actuation of the innermost element of this series, I connect it to the adjacent element of said series by means of a link 55, pivotally connected to lugs 56 projecting rearwardly from these elements adjacent the lower edge of said innermost element.

The actuating bars 54 carry upstanding studs 5'7 which extend through openings 58 in the plate 46, configured to permit movement of the studs 57 during the opening and closing of the shutters. The studs 57 are connected by links 59 to bell crank levers 60, the other ends of which are provided with slotted openings 61. In these openings is received a pin 62 carried between the legs of the bifurcated end of a rod 63 which extends forwardly from a thermostat 64. The thermostat 64 is preferably located Within the liquid chamber of the radiator above the core 12 so that it is actuated in accordance with the temperature of the cooling medium in the circulatory system of the engine. It will readily be understood that when the thermostat 64 expands under the influence of increasing temperature, the rod 63 is projected forwardly, actuating the shutter elements 33 through the bell crank lever and the links 59 so as to open them. Springs 65 connected to the plate 46 and to the links 59 oppose this opening movement and effect the closing of the shutter elements when the temperature falls below a predetermined point, so that the operation of the shutter is automatic.

Although the invention has been has been disclosed in connection with the specific details, of the preferred embodiment thereof, it must be understood that such details are not entitled to be limitative of the invention except insofar as set forth in the accompanying claims.
